- 1989 Bronco II
Hi, I have a 1989 Bronco II with a 2.9. It will randomly loose power and backfire. When this happens is usually during deceleration and the truck will reek of gas and idle at 2-300 RPM. When i turn off the beast it will restart but run rough. When you give her some throttle it revs to 1000 rpm and then drops back to 2-300 rpm. If the truck sits for 5-10 min it will restart and run fine. I have replaced the plugs, wires, cap, rotor, ignition module, coil. Fuel pressure reads 40 psi when it dies so im thinking its not the fuel pump. Catalytic converters have been removed and the fuel filter has been changed. I dont know what to try next? Computer, o2 sensor, MAP sensor, fuel pressure reg????? No idiot lights come on and there are no codes... I'm lost.
Thanks for the help
